Definitions

  • the invention relates to a device for controlling a fully sequential gas system for diesel engines, especially for commercial vehicles.
  • the device according to the invention consists of an injector strip (6), which supplies each individual cylinder separately with the required amount of gas. These may be mechanically, electrically, magnetically or piezoelectrically controlled injectors.
  • the gas is supplied by liquid gas from the tank container via an evaporator (LPG) or pressure regulator (CNG) is converted into the gaseous state. It then passes through a filter system directly to the injectors, wherein before the injector a pressure measurement (5) is made to control.
  • LPG evaporator
  • CNG pressure regulator
  • Each cylinder is controlled individually (11) and supplied with the required amount of gas.
  • a pressure sensor (5) is required according to the invention, which determines the pressure of the compressed intake air (3). Furthermore, a pressure measurement of the supplied gaseous liquid gas component takes place in front of the injector bar. Also new for the control of the gas system in diesel operation is the signal acquisition via a knock sensor (15).
  • control unit detects and processes the following signals and parameters via suitable sensors: signals from the knock sensor (15), signals from the crankshaft sensor (16), signals from the CAN bus (17), pressure measurement in the intake air (5/3), signals from the Foot pedal sensor and the injection pump, signals from the lambda probe (18), parameters that are measured in the exhaust system, such as temperature, pressure, NO x content, HC and O 2 content.
  • FIGS. 1 and 2 An inventive embodiment of a gasoline plant for diesel engines is in the FIGS. 1 and 2 shown.
